This is REALLY annoying...during rides of more than 3 hours the magnetless cadence sensor disconnects and stops working altogether. Occasionally, I get an audible signal and a message that reads, "Cadence sensor detected." The screen on my Garmin 800, however, shows the dreaded _ _ _ in place of the cadence reading.
I have tried every possible work-around, replacing the battery, cleaning out the electric contacts, moving the position of the sensor on the crank arm, clearing the memory on the Garmin 800 and even lighting votive candles to Mr. Campagnolo and Mr. Shimano. Nothing works.
I really like to use the cadence feature, it is like using a tachometer in a manual transmission car, it tells me how I am performing.
Any solutions out there?
